In-game description

Vizzik Skour, Lord of the Gnaw, Prophet of the Horned Rat, Master of the Death Frenzy. Formed from proto-flesh by the Great Horned Rat in the apocalyptic wake of the Vermindoom. He rose from the Masterburrow after the bells of Blight City tolled an ominous thirteen times. The force of his zeal is enough to drive his enemies utterly mad. All according to the Great Horned Rat's will.

Wounds

Its Wounds are your level x 650, at least 10,000, times the stage and mode multipliers. Corruption does not raise them.
